基于有限元法的活塞杆反向车削工艺研究

Study of Reverse Turning Process of Piston Rod Based on Finite Element Method

活塞杆是典型的细长轴零件,车削时为了提高车削加工质量,根据生产经验优先选用反向车削。为对细长轴反向车削提供理论依据并对加工质量进行量化,分别从理论分析、试验验证的角度开展研究,结果表明细长轴反向车削较同工艺参数条件下正向车削的加工质量提高约5%-10%,更容易满足细长轴的加工技术要求。

Piston rod is a typical slender shaft part. In order to improve machining quality, reverse turning is preferred according to production experience. The paper provide a theoretical analysis basis for the reverse turning of the slender shaft and quantify the processing quality. The results show that the reverse turning of the slender shaft is about 5% - 10% higher than that of the process parameters.
